一种新型的减摩耐磨复合电镀层

A NEW TYPE OF ANTIFRICTION AND ANTIWEAR ELETRODEPOSITED COMPOSITE COATING

利用复合电镀方法将ＴＮＴ／ＲＤＸ（５０／５０）混合炸药爆炸后生成的爆炸黑粉（由超微细石墨、金刚石及无定型碳组成）与Ｎｉ共沉积制备了Ｎｉ基复合电镀层．实验结果表明：复合电镀层呈非晶化趋向，其硬度和耐磨性能明显改善，而且还具有较好的自润滑性．

The black solid powder consisting of ultrafine diamond, graphite and amorphous carbon was synthesize using the detonation method of TNT / RDX (50 / 50) mixed explosive, and the Ni-black powder electrodeposited composite coating (ECC) was prepared. Experimental results showed: comparing with Ni and Ni-graphite coatings, the Ni-black powder ECC was showing an amorphous tendency, its microhardness and antiwear performance increase obviously, and it possessed the better self-lubricating property.Correspondent : YAN Fengyuan, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000
